HP ProLiant DL380e Gen8 instaled ESXi 5.5.0 Build 2068190 on internal 8GB SD card PSOD problems

I have new server, new instalation.

Inside i have 2 EG0600FCSPL disk in RAID 1

There are curently running 3 VM. 2 Server 2012 R2 and one Windows 8.1 VM.

First i got PSOD 14 days ago, and it poped up during instalation. I updated firmwere diretly from server.

Now when server is rdy to start runing (domain is UP, computer in domain etc..) i got PSOD again yesterday. After reading some forums, may be problem with HP power saving futures. I set all on high preformance. At night got new PSOD,In attachment ares PSOD's from yesterda and this night.  All were about "No heartbeat".

I am also noticing when i log to the server in the morning, it need like 30 sec to get log in. After firt login is taking like 5 sec, much faster. This i am noticing from start till today. Maybe is conected with someting.

 

Any idea what can be wrong ?

Tnx

Repeated com.vmware.vcHms messages to install vr2c-firewall.vib

Hi All,

 

Running vSphere 5.5, vCenter 5.5 and SRM 5.8.  Every time a host goes into or out of maintenance mode we see an install happening from "com.vmware.vcHms".  Looking at /var/log/esxupdate.log I see a message showing a connecting to the replication VA :

 

esxupdate: downloader: DEBUG: Downloading from https://a.b.c.d:8043/vib/vr2c-firewall.vib...

 

This is also happening over the WAN and it's not desired.

 

Any ideas on how to prevent this from happening on hosts that are not participating in SRM or vSphere Replication?

Large disk vm's and snapshots

January 2, 2015, 6:47 am

My entire environment is 5.1, and the platform we use to back up virtual machines takes a temporary vsphere snapshot to do so. I've had to deploy some rather large vm's this past year (400GB +), and backing them up in this manner has caused problems for us on occasion. I realize snapshots can decrease performance, but for the time being I need a way to ensure these vm's are backed up while minimizing performance impact.

 

On a few different occasions, I've had production servers affected to the point of being unusable for their purpose, but my hands were tied until the snapshot (slowly) got removed and the disks consolidated. I even had one incident where the snapshot removal was hung/interrupted/severed causing nearly three hours of downtime while the cold (recommended by our support) disk consolidation took place.

 

Until I can convince my manager to go the VEEAM route which seems to be ideal for our situation (take full back ups directly from storage snaps instead), does anyone have any thoughts or suggestions, or am I just stuck with these performance problems on the larger vm's?

 

Thanks!

VM Consolidation freezes at 99% after 3 hr run time

Good Morning,

I have the following severe issue.  A server had a snapshot which ended up continuing to grow, now the datastore which hold the VM is full.  Upon removing the snapshot and running a disk consolidation, it freezes at 99% and then eventually disappears.  The issue is this server so roughly 1TB and no other datastores in the cluster can handle a migration.  I've thought to clone it as this should run the consolidation however all I have is an external usb HD to use for creating an additional datastore.

VMware ESXi 5.5 crashing

I have a server with ESXI 5.5 and two virtual machines running pfSense, the problem is that almost every morning the server crashes, I can not even access the virtual machines or the own server by the vSphere Client. What could it be? Hardware problem? Or otherwise virtual machines can cause the host crash? Thanks

Disabling write caching in guest VM - recommendations?

January 2, 2015, 10:23 am

Hi folks

 

We're using a few different technologies which rely on VMware snapshots to take backups and/or copies of our Windows virtual machines (let's stick with NetBackup for the purposes of this discussion)

 

The backup software hooks into vCenter and requests that it trigger a snapshot of the VM. The backup software then copies the snapshot and finally requests that vCenter delete the snap. Easy-peazy.

 

These are crash-consistent backups. If I ever have to restore a complete VM, when I power it up, the guest OS (Windows) will act as though it had experienced an unexpected shutdown.

 

My question is regarding the implications of the "policy" setting in the properties of a disk in Windows, and of changing this policy to disable write caching. I would think that this would be desirable for any machine where I'm taking these backups, because it means that the guest OS will dump everything to disk immediately, thus reducing the potential for corruption / data loss in the event that I have to recover a machine from one of these backed up snapshots.

 

I did a lot of Googling on this topic but haven't seen anything which really addresses it from this angle

 

Thoughts?

Has anybody gotten Intel onboard SATA passthrough working in ESXi 5.5?

The last time I tried (with 5.5U1) it worked if the VM was installed and booted via UEFI rather than BIOS, but unfortunately that led to a whole host of other issues and I ended up having to downgrade back to 5.1.

 

Has a workaround been discovered in the months since? Or better yet, can anybody confirm if VMware has fixed this in 5.5U2?

RDM pyhsical passthrough of disk problem with partition type 0xfd (raid autodetect arrays)

I tried to passthrough my synology nas disks with partition type 0xfd.

vmkfstools -z vmfs/devices/disks/t10.ATA_____ST2000DL0032D9VT166__________________________________XXXXXXXX /vmfs/volumes/datastore1/RDM/NAS2TB_1_XXXXXXXX.vmdk -a lsilogic

results in: Failed to create virtual disk: The specified device is not a valid physical disk device (20).

 

The reason seems to be the partition type 0xfd (raid autodetect arrays). This problem is shown with the disk itself.

Any idea how to solve it?

 

P.S.:

I also tried to passthrough my onboard sata of my intel DH87RL Lynx Point AHCI, but it failed when connecting it to the VM:

HP P2000 G3 iSCSI - very slow read performance

January 3, 2015, 12:45 pm

Hi all,

I have DL380 Gen8 server with P2000 iSCSI array - dual controllers, 1GB version. iSCSI traffic is going through separate switch, with 2 server ports and all array ports. Using ESX 5.5 build 2302651. I followed HP best practices and tons of guides, using RR with iops=1 (but tested also other options). iSCSI setup is tested several times against VMware/HP whitepapers and it works, as well as load balancing, confirmed using esxtop.

Currently I have test Centos 7 machine, with tuned-adm applied, XFS layout. Testing with iozone, no matter what and I how I change, I'm getting sequential reads close to max 2x1GB interfaces: 245MB/sec, but read performance is maximum 150MB/sec. I tested various disk layouts on P2000, the best seem to be RAID10, but interestingly it doesn't change much between RAIDs, I have pretty much the same write performance on RAID5, just worse read, down to even 20-30MB/sec. Surely, P2000 with 12 10k SAS disks should be better than this.

I've spoke with HP support, they've seen array logs and they say it's all good over there and it's rather VMware problem, but honestly I can't find it and I'm out of ideas. At the moment I'm using RDMs, they are somewhat faster, with VMware paravirtual scsi controller. I also tested Centos 6.6 and Windows 2012, in fact Windows is even worse than other two.

Any hints from you guys what might be wrong with my setup?

Many thanks

Chris

I cant get my kickstart command to install on the iscsi disk.

 

the line

 

install --firstdisk=remote says not sutable disk found

 

I also tried

 

 

 

install --disk=/vmfs/devices/disks/eui.xxxxxxxxxxxxxxxxxxxxxxxxx

 

 

install --disk=mpx.vmhba32:C0:T0:L0

 

 

none of these sees the iscsi disk

 

 

but if I run the installation manually, I do see the iscsi disk.

 

 

any idea?
